There are some improperly intersected beams. You can identify those beams by going to Geometry -> Intersecting Beams -> Highlight Intersecting Beams. To intersect those beams properly, select all members in the floor and go to Geometry -> Intersecting Beams -> Intersect Selected Beams.

I have then used such ranges to apply the floor load at level Y = 11.45 m:

YRANGE 11.4 11.5 FLOAD -2 XRANGE 3 21 ZRANGE -12 1 GY
YRANGE 11.4 11.5 FLOAD -2 XRANGE 20.5 33.5 ZRANGE -15 3 GY

No, I am not applying the floor load on the sloped part of the roof. I am applying it to the normal slab part. the roof is made up of steel and the part where I am applying the load is of concrete. It is rectangular in shape. There are different trusses that are resting on the rectangular slab part. I am applying the floor load on the rectangular slab part but the trapezoidal load distribution is not happening there. I am attaching a picture for your reference.

Are you trying to apply te floor load on the sloped parts of the roof? In that case instead of using ranges to define a polygon where floor load needs to be applied, create a Group of members with the Type set to Floor and apply the floor load to that Group. Each slope should have a separate group.
